Sergio Agüero is expected to return to training with Manchester City as scheduled despite the “dizzy spell” he endured at half-time during Argentina’s friendly defeat against Nigeria in Krasnodar on Tuesday night. The forward was due to fly home on Wednesday following the 4-2 defeat and take part in his scheduled session with Pep Guardiola’s squad. Agüero was taken to hospital in the Russian city as a precaution, with the club later stating that Agüero had encountered a “dizzy spell”.
